Brexit: How Will UK Agriculture Fare?

There is little doubt that Brexit would have significant implications for UK agriculture, a sector with strong trade links to the EU and strong reliance on CAP income support. This article reports preliminary results from employing a Computable General Equilibrium Model, a Partial Equilibrium Model and Farm Level Models to explore selected trade and domestic policy scenarios post‐Brexit. These allow for the estimation of changes in producer prices, production and farm incomes against a baseline scenario of continued EU membership. Under a Free Trade Agreement with the EU, agricultural impacts are relatively modest. By contrast, unilateral removal of import tariffs has significant negative impacts on prices, production and incomes. Adoption of the EU's WTO tariff schedule for all imports favours net importers (e.g. dairy) and harms net exporters (e.g. sheep). Given the strong dependence of most UK farms on direct payments, their removal worsens negative impacts of new trade arrangements and offsets positive impacts. Impacts vary across different types and sizes of farm, but also regionally. However, the period of adjustment to new trade and domestic policy conditions may prove very challenging for a large number of farm businesses.     

Conditioning manager alphas on economic information: another look at the persistence of performance

This article presents evidence on persistence in the relativeinvestment performance of large, institutional equity managers.Similar to existing evidence for mutual funds, we find persistentperformance concentrated in the managers with poor prior-periodperformance measures. A conditional approach, using time-varyingmeasures of risk and abnormal performance, is better able todetect this persistence and to predict the future performanceof the funds than are traditional methods.     

Nile perch and the hungry of Lake Victoria: Gender,status and food in an East African fishery

Lake Victoria supports Africa’s largest inland fishery, and its most valuable product is the Nile perch, much of which is exported. This has given rise to arguments claiming a direct linear relationship between perch exports and disturbingly high rates of malnutrition along the lake’s shores. In this paper, we argue that this argument is seriously flawed for it is unable to explain how it is that the income from the Nile perch fishery fails to translate into a well-fed riparian population. We draw on field work carried out in 2001 that (a) set out to establish exactly how much malnutrition there was on the lake’s shores; and (b) sought to identify what happened to the income the fishery generates. We argue that because men control much of the fishery, and women are held responsible for the upkeep of their families, little of this income makes its way back into the households of the region, giving rise to the levels of malnutrition we observed.     

US domestic airline alliances: does the national welfare impact turn on strategic international gains?

The six largest U.S. airlines announced in the beginning of 1998 the formation of three domestic alliances, but the size and scope of these alliances spurred significant public interest concerns. GAO analysis suggests a rough equivalence between the domestic costs and benefits of alliances, yet the international competitive effects have not been considered. I argue that the national welfare merits of domestic airline alliances turn on positive international competitive effects. Empirical tests - run on comprehensive panel data covering the international airline markets among 21 nations over the 1983–1992 period - support domestic market concentration resulting in strategic international gains; hence, domestic airline alliances likely improve national welfare.     

Characteristics of non-fatal injuries in Leon, Nicaragua - 2004

This article describes the epidemiology of injuries collected in the Injury Surveillance System in Leon Hospital in Nicaragua. A total of 6659 persons were treated for injuries in 2004. It was discovered that 88% of all injuries were unintentional, 9% involved interpersonal violence, 2% were self-inflicted and 0.2% was undetermined. Men accounted for 64.7% of the cases, with the highest rate among 20 - 24 year olds (5625.8 per 100,000 inhabitants). Among women, the highest rate was in those aged 64 years and older (5324.2 per 100 000 inhabitants). The most common mechanisms were falls (33.9%), blunt force (26.8%), cut/pierce/stab (15.1%) and transportation-related (12.8%). These results indicate the need to identify prevention strategies for those injuries that were most commonly treated in emergency, such as unintentional falls among older women, self-inflicted poisoning among young women and blunt force and transportation-related injuries among young men.     

The Influence of Perceived Justice on Recovery Satisfaction in the Airline Industry

This study examines the influence of perceived justice on customer satisfaction with service recovery and on the future behavioral intentions of customers in the airline industry. The study uses an exploratory research design that is quantitative in nature. Questionnaires were used to collect data, and structural equation modeling was used for hypothesis testing. The study revealed that the three dimensions of perceived justice, namely interactional, distributive and procedural justice, influence satisfaction with service recovery in the South African airline industry. However, only interactional and distributive justice had a positive influence on future behavioral intention.
